Abstract:
Shi et al. have applied an equation for solution
equivalent conductivities (denoted by A) to the problem
of estimating species equivalent conductivities (denoted
by A.), with potentially pathological consequences, as I
will show. For completeness, I will address some of Dr.
Shi's statements one at a time: Estimation of the
electrical conductivity of mixed solutions. ..is
discussed and demonstrated in most physical chemistry
and electrochemistry textbooks. Actually, the electrical
conductivity of solutions composed of binary salts is
discussed in most textbooks. As these are textbooks,
they typically limit the discussion to simple salts and
leading order concentration dependence. Most textbooks
give Kohlrausch's equation for the solution electrical
conductivity A.
